This invention relates to 'eoii v'e'yere and more especially to chutes;and the blijct of the seine is t0 prfvi'de means tee reterdiiig thespeed of articles er materials s1i ="=g down a -chute. This object*arried me; by providing the bottom of the ehete with riflles composedof ropeflcehlefor iossibly of chain, in contra-dist dfion te ms weeteh 7trated in the d1ejvi rigs'Whe' battens or slats Wlli hiihfi hithertobeen used; The following specification sets forth several Ways ofcarrying but ide es illus- Figure 1 is a. plan fvi 'w o f tl rechu tepro"- vided with ohiiqu'e rifii-es tomedereep rove through hoies in thechute.

Theremaining view sure plan's po'lnti ons of e chute, showing veri'ousmeens "for carrying out the same idea; In Fig: 3 is Wire "white isemployed, roi'ie throughho le's iii thebottoinf of the chute sain dl'with its upper stretches permitted to have a certain slack rather thafhbeing drawn timtas in -1-.

In Fig. 5 the member 9 might be a this View hasheen usedto show that itcould be extremely; 'sl-ack ifdesired end that its lower stretches 10eoulfd ruh parallel with the sides S." i Q Thes three views, Figs. 4 5,shew andthe samer o' pe 3 although the latter is r h'eheeth the. hottoniB. The 'heies 1' aii' d 2 fierent "effect on em g e,

' are unobstructed. I do not wish to be lini ited in this respect.

Fig. 6 shows still another way in which the idea may be carried out, andherein the member 11 isstretched straight across the bottom B andthrough the sides S, being knotted or fastened at the outer ends as at12 in any suitable manner, or perhaps carried down as at 13 and passedback across the bottom as indicated at 1%. Here said member will ofcourse extend completely across the fullwidthof the bottom B, and it maylie upon the same or be disposed slightly above the same, and it mayextend straight across or obliquely across, as desired. Also it will beclear that one stretch may extend obliquely across the chute in onedirection and the next obliquely across in the opposite direction, withor without an interposed stretch which would extend straight across.

The idea is susceptible of a variety of modifications, and as it isquite obvious that the flexible member could be any which will answerthe purpose I do not wish to be lim ited in this respect.

In use, the chute is employed in the cus tomary manner, supported in anyway desired, and used in lengths or in one piece.

' The article or commodity handled may be any which it is desired tohave the chute convey. The face of the bottom B and the inner faces ofthe sides S are smooth, and the holes 1 and 2 may be formed in any suitable manner. When it is found that the cargo passes too rapidly alongthe chute, this improved retarding device may be ap plied. If it is in along piece, it is rove through the holes in any of the ways described orin any suitable way, and its extremities tied or fastened in somemanner. if the flexible member is in short pieces, its ends 5 are passedthrough the holes as seen in Fig. 2 and knotted or otherwise fastened asat 6 to prevent the pieces from becoming lost out. The size of theflexible member and the character thereof will depend upon the usage towhich the chute is to be put and the amount of retarding effect it isdesired to produce. The cargo or articles are then sent down the chute,and as each one strikes one of the upper stretches of the flexibleelement it is retarded more or less according to its nature and thenature of the element. If

' the latter be inclined the cargo is directed Copies of this patent maybe obtained for straight across the cnatewhether taut 0i it can bereplaced without stopping the use of the chute. The use of individualpieces or strands may therefore be said to be pref: erable for thisreason, and for theifurther reason that a piece or stretch could beremoved here and there in case it was found that the retarding eflectproduced was too serious or too severe.

"While I have described this invention as applied to a chute and such ismy present purpose for its use, it is quite possible to use a retardingdevice of this or a similar structure in other places where baffles orbattens are now commonly employed, and 1 do not wish to be limited inthis respect.

What is claimed as new is:

1. The combination with a chute having holes at intervals therein; of abaffle consisting of a rope rove in and out through said holes with itsupper stretches inside the chute and overlying the face of its bottom,and means for holding the rope in place.

- 2. A baffle for chutes and other inclined elements down whichsubstances are to slide. the same consisting of a flexible memberextending across the bottom of said element in stretches with both endsof each stretch connected with the bottom.

3. A baffle for chutes and other inclined elements down which substancesare to slide, the same consisting of a rope rove through holes in saidelement with its upper stretch extending obliquely across the facethereof.

1. The combination with achute comprising upright sides, and a bottomhaving holes therein; of a bafiie consisting of a flexible member rovethrough saidholes with its upper stretches extending across the face ofthe bottom and its lower stretches underlying the same.

5. An inclined chute comprising a bottom and upright sides, combinedwith flexible baflies disposed atintervals along the chute and extendingacross the face of its bottom and nearly to its sides.

6. A chute comprising a bottom and upright sides; combined with bafflesdisposed within thechute oblique to its length. overlying the bottom andextending nearly from side to side so as to leave narrow paths past suchbaffles along the edges of said bottom.

In testimony whereof I affix my signatm-e in presence of two witnesses.
